To all whom it may concern:

Be it known that 1, EDWARD NUEBLING, a citizen of the United States, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Window Screens, of which the following is a specification.-

This invention relates to window screens and has for its principal object to provide a new and improved construction of an extensible window screen, the sections of which are pivotally mounted to an extensible supporting frame so as to permit the screen to be opened without necessitating the removal thereof from the window frame.

Another object is to provide means for locking the pivotally mounted sections of the screen in operative position. A further object is to so construct-the window screen and frame therefor that the window opening will be free and unobstructed when the sections of the screen are swung upon their pivots to opened position. 7 l, v

Another object is to provide the outer supporting frame with means for quickly and easily securing or removingscreen to the window frame.

For the accomplishmentof these and such further objectsas will be apparent to those skilled in the art to which this appertains the invention consists in the construction, combination, and arrangement of parts, as hereinafter more fully described and as-illustrated in the accompanying drawings forming a part hereof, and in which the examples are shown as illustrating but not as limiting the principles of my invention.

Referring to the drawings Fig; 1 is a front elevation of my improved window screen inpartly extended operative position.

Fig. 2 is a top view of the structure shown in Fig. 1.

' Figs. 3, 4 and 5 are sections 011 the lines 8-3, 44 and 55 respectively of Fig. 1.

Fig. 6 is a view similar of Fig. 1 of a modified form of construction.

Fig. 7 is a top view of the structure shown in Fig. 6.

Fig. 8 is a detail top view showing a modified construction for permanently securing the screen to the window frame, and Fig. 9 is a sectional detail.

As shown in Figs. 1 to 4 ofthe drawings an outer supporting frame is composed of a pair ofextensible' sections, each consisting of a vertical upright 11 having a horizontal cross bar 12 secured to the lower end thereof. One of the cross bars 12 is provided with a dovetailed guideway 13 in which a tongue 14, projecting laterally from the other of said cross bars engages. A screen 15 formed by the extensible sliding sections 16 and 17 is pivotally secured, adjacent to its corners, to the supporting frame by the followin means.

The junctions of the cross bars 12 with the uprights 11 are reinforced by the corner plates 18 each of which has a horizontally extending web 19 which, is seated within a recess cut into the top face of the cross bar so as to bring the upper face of the web flush with the cross bar. Each of the two lower corners of the screen 15 is provided with a reinforcing corner plate 20 having ahorizontally extending portion 21 which extends across the lower face of the screen frame and is seated within a recess cut in the frame similar to the recess provided in the outer supporting frame for the web 19. A spring tongue 22 integral with the portion 21 is bent backwardly upon said portion, as clearly shown in'Fig. 1 of the drawing to lie between said portion and the web 19. As shown in Fig. 3 of the drawing the web 19 is curved to presenta convex surface on its upper face and the spring tongue 22 is similarly curved so that the sections of the screen will be held resiliently with the outer frame.

A pivot or hinge pin 23 having an enlarged head 24; is secured by the portion 21 to the screen and projects through the spring tongue 22 and the web 19 into a hole 25 in the outer frame.

Each of the upper corners of the screen 15 is provided with a corner plate 26 similar in construction to the bottom corner plates except that the tongue 27 which is bent backwardly upon itself in the same manner as the spring tongues 22 is not curved transversely. The main function of the bent tongues 27 used at the upper corners of the screen is to provide a doublebearing for the upper pivot and hinge pins 28, which it will be noted extend through a tongue 29 formed integral with and extending laterally from an end bracket 30 secured to the upper end of the uprights 11 of the outer supporting frame.

The end brackets 30 are provided with a boss 31a short distancefrom the top thereof in which a thumb screw 32 is mounted. Screw 32 has secured to its outer end the thumb piece 33, to which is pivotally secured the serrated disc 34. Similar thumb screws structure is extended to the full width of the Window sash guideway. The catch 35 is now swung to the dotted line inoperative position shown in Fig. 1 and the screen sections 16 and 17 are swung upon their pivotal mounting to their opened positions to permit free access to the thumb screws, which areadjusted to clamp the, outer supporting frame securely in position within the sash guideways. It will be noted that the screen sections 16 and 17 may be swung either inwardly or outwardly and that the spring tongues 22 while holding the sections, in their closed position, will also permit them to be opened and will bear against the webs 19 with a sufficient pressure to hold the screen sections in opened position, thereby preventing the sections from swinging to the closed possition when the screen has been opened to raise. an awning or for any other purpose. As no upper cross bar is used in the outer frame it will be noted that a clear unobstructed window opening is secured when the screen "sections are moved to opened positions.

In the form shown in Figs. 6 and 7, an upright 40 is provided at only one side, to which upright, the extensible screen 41, composed of the sections 42 and 43, is pivotally secured as by means of the slip hinges 44.

The upright 40 is secured within the sash gu'i-deway in this form by means of thumbs screws 32 and serrated discs 34.

hen it is desired to open the-screen the section is slid to the righta su'ilicicnt dis:

stance to clear the outer g-uideway strip 45' and thereby allow the screen to be swung outwardly upon the hinges to opened position. i

In the form shown in Fig. 8 the construe tion of the extensible screen is similar to that show-n in Figs. 6 and 7, but the upright 40 is permanently secured to the. ,outer guideway strip 45 as by means of the screws 46. A turnbutton 47 is pivotally secured to the side of the screen opposite to the upright 40 for the purpose of locking the screen in closed position."

In vFig. 9 is illustrated an application of a flexible strip 50 of felt, rubber or other suitable material to close the gap which would othewise be present between the top of the screen and the sash. This construction is particularly applicable to the forms shown in Figs. 6 to 8 inclusive but would not usually be required with the construction shown in Figs. 1 to 4.

It will be understood that the various means for securing the screen to the win dow, such as the screws 32 to 46 are merely illustrative and that any equivalent means may be employed.

Having thus described my invention I declare that what I claim as new and desire to secure by Letters Patent of the United States is,
